A boolean value denoting whether or not to collect the “info” metrics that
describe the state of the whole HAProxy process, metrics such as uptime seconds,
current total connections, size of the run queue, etc.

Flag for whether to collect proxy “stats” metrics. These are detailed metrics
for individual proxies in HAProxy, such as HTTP status 200 response count, bytes
in/out, queued request count, etc. The full list of metrics available can be
found in the HAProxy ‘show stats’ docs.
